I would try looking where they have been found on the later tanks. Mine only took about 15 minutes to get to trhough previous owners undercoating and paint. A generous shot of paint remover, followed by scraping and sanding.

I looked at my original 67 02B tank and cannot find any date code. Are they supposed to be in the same place as 68 & 69??

I would think so but seems kinda funny NO ONE with a 67 has chimed in so maybe not??? I always look for silly stuff like this when I go over a really nice car just to see how "real" it is but can't say for sure because my passion is 68's so I really don't lock into memory what I see on 67's or 69's unless it's something out of the ordinary. I do know some of the stamps can be dam near impossible to see, if you really want to see if there's anything there, try pulling a razor blade flat across the corner of the tank a FEW times, blow area off-don't wipe!, and get a flash light and shine/look from all different angles. If the tank is still in the car a small mirror will help get better angles. Actually just try the flashlight/mirror trick first, and use the razor blade as last resort!!!
